Altered States by David Regal - Trick

An easy-to-do, offbeat card routine that never fails to impress. A card, selected from a blue-backed deck and signed across its face by a spectator is torn in half. One half is placed in a blue card box and the other in a red card box. The spectator's partial signature is on the face of both halves. The card boxes are shaken and the cards dumped out. The half that came out of the blue box still has a blue back, but the card out of the red box now has a red back. The two halves fit together and so do the two parts of the signature. Everything can be immediately examined and the two half-cards can be given to spectators as souvenirs.

Comes with fifteen (15) Half & Half, Poker-size, Bicycle cards printed by the U.S. Playing Card Co. and photo-illustrated instructions. Can be repeated three times with different cards.
